Maps a range of upstream items to a range of downstream items. The range is determined by two main properties: the ratio of upstream work items to downstream work items, and an offset in the left and right direction.
For example, with Upstream Range set to 2 and Downstream Range set to 1, two upstream items will be mapped to each downstream item.
Use Dynamic Mapping
By default, a mapper will establish dependencies between upstream static work items and downstream static work items. When this toggle is enabled, a second mapping pass will be done between any dynamic items above the mapper and static items below the mapper.
The dynamic items will be prefiltered based on the static mapping defined by the node, such that only dynamic items that descend from the selected static items will be considered.
Along with the Downstream Range parameter, determines the ratio between upstream and downstream work items.
Determines the number of downstream work items for each group of upstream work items specified in the Upstream Range parameter.
The number of additional items proceeding the selected items that should also be mapped to the downstream items.
The number of additional items that follow the selected items that should also be mapped to the downstream items.
This example demonstrates how to use the Map by Range node to establish dependencies from downstream to upstream based on workitem index.
The following examples include this node.
